To connect the external alarm indicators and the auxiliary power:

1.Connect 1 major (Brown-White and White-Brown) and 1 minor (Orange-White and White-Orange) alarm input pair to the trunk/auxiliary field from the TN2312BP Adapter DB9 alarm connector. See Table 14: Alarm Inputs at TN2312BP Adapter DB9 Alarm Connector on page 90. Alarms can be generated on adjunct equipment, sent to the Avaya media gateway, and recorded and reported as “external alarms.” The adjunct equipment must provide an isolated contact closure across the alarm leads provided by the Avaya media gateway. The contact must be rated at a minimum of 60 VDC with a current carrying capacity of 5 mA minimum.

2.Connect an external alarm output (Green-White and White-Green).

3.Note which device connects to which alarm and give this information to your Avaya representative for troubleshooting purposes.
